YamaYoga has a great set of classes all 7 days of the week, and each one I've taken has been beneficial. The instructors are quality, well trained and down to earth, while the introductory offer that Yama gives is worth trying. If you pay only $10- you get ten consecutive days (over a full WEEK) of Yoga. So then you get to try out all of the classes they offer, for many different levels. Bikram and Anusara methods included.
After experiencing Bikram at several studios in the Chicagoland Area, this was a major disappointment. First of all, the studio is certainly not set up for a "hot" environment. To heat the room as it should be (105), they use multiple space heaters around the room and clip heat lamps to the walls. It definitely was NOT 105 in there, and the heaters add clutter to the already small studio. There is only 1 wall containing mirrors, and with a crowded room, it makes it very difficult to find a view point. Furthermore, the instructor had poor timing and took a more negative approach than most of the obviously experienced Bikram instructors, I've found in the past. I found the class to be a "faux" Bikram, overall, and was definitely disappointed by the whole experience.
Pros: convenient to downtown
Cons: parking, ambiance, instructor, class
